package loop; public class TestLoop2 { public static void main(String[] args) { int p = 100; do { while(p>100) { System.out.println("I am in while"); } System.out.println("I am in do-while"); } while (p > 100); } }

  1. I am in do-while

  2. I am in while I am in do-while

  3. Compiler Error

  4. No output


Correct Option: A

package loop; public class TestLoop3 { public static void main(String[] args) { int p = 0; for (int i = 0; i < 3; i++) { p = i+1; if (p == 2) { continue; } System.out.println("i in loop = " + i); } } }

  1. i in loop = 0 i in loop = 1 i in loop = 2

  2. i in loop = 0 i in loop = 0 i in loop = 1 i in loop = 2

  3. i in loop = 0 i in loop = 2

  4. Compiler Error


Correct Option: C

package loop; public class TestLoop1 { void testFor() { for (int i = 1; i < 3; i++) { System.out.println("i in for loop = " + i); if (i == 1) { break; } } System.out.println("For loop over"); } public static void main(String[] args) { TestLoop1 tl = new TestLoop1(); tl.testFor(); System.out.println("Method call Over"); } }

  1. i in for loop = 1 i in for loop = 2 For loop over Method call Over

  2. i in for loop = 1 For loop over Method call Over

  3. Compiler Error

  4. i in for loop = 1 Method call Over


Correct Option: B

package overriding; class Super3 { void testDivide(int i, int j) throws Exception { double p = i / j; System.out.println("p in Super =" + p); } } public class TestOverrideSub3 extends Super3 { void testDivide(int i, int j) throws ArithmeticException { double p = i / j; System.out.println("p in Sub =" + p); } public static void main(String[] args) { Super3 s3 = new TestOverrideSub3(); try { s3.testDivide(10, 5); } catch (Exception e) { System.out.println("Exception " + e.getMessage()); } } }

  1. p in Super =2.0

  2. p in Sub =2.0

  3. Compiler error

  4. Exception


Correct Option: B

package overriding; class Super4 { final void testSuper() { System.out.println("I am Super"); } } public class TestOverrideSub4 extends Super4{ void testSuper() { System.out.println("I am Sub"); } public static void main(String[] args) { Super4 s4 = new TestOverrideSub4(); s4.testSuper(); } }

  1. Compiler Error

  2. I am Sub

  3. I am Super

  4. Exception

(Choose two.) author Elmore Leonard public class ContextInitParms extends HttpServlet { protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/html"); PrintWriter out = response.getWriter(); Out.write(""); ServletContext sc = getServletContext(); out.write(sc.getInitParameter("auther")); out.close(); } }

  1. ParameterNotFoundException is thrown.

  2. Some other exception is thrown.

  3. "Elmore Leonard" is output on the web page
